Title: Improvements in or relating to the production of thread and particularly artificial silk thread
IPC: D01D10/04
Filed: 1936-02-07
Abstract: <PICT:0474973/IV/1> Apparatus for producing thread, particularly artificial silk thread, comprises a number of devices or reels adapted to advance the thread in a large number of generally helical turns disposed in end-wise stepped relation.  Each reel is mounted on a shaft which does not project beyond one end face of the reel as described in Specification 474,974.  The axes of all or substantially all of the reels are preferably in the same plane, preferably a vertical plane, thus giving an inclined bank effect to an assembly. A machine for producing and treating artificial silk is shown in Fig. 4, filaments from a spinning-bath 2 passing to a reel 5 and thence in succession to reels 5a ... 5h associated with treatment apparatus, and a drying reel 5i to cap twisting-spindle apparatus 7, the reels being of the same form as those described in Specification 413,414, [Group IX].  The machine is double-sided, platforms 8, 9 being provided to permit access by the operative to the mechanism.  The driving-motor is mounted at one end of the machine and is coupled through reduction gear 19 with a cross-shaft 20, which drives an inclined shaft 23 coupled to the reels and pumps by means of gearing 21, 22, and drives the building-motion cam 125 of the twisting-apparatus by means of gearing 123.  The spindles of the twisting-apparatus are driven from a roller 119 which is driven by a belt 121 directly from the motor or through the reduction gear.  The shaft 23, by means of a spiral gear 24 and a counter shaft, drives the pumps through sprocket and change gear 33, and the first reel 5 through sprocket and change gear.  The other reels are similarly driven through change gear and clutches which <PICT:0474973/IV/2> collecting-troughs 108 by pipes leading, in the case of wash water and the like to the sewer, and, in the case liquids which may be used again, to a collector from which they are delivered to the distributers.  The reels comprise a member 80, Fig. 6, rotating with a shaft 72 and provided with integral bars 82 embracing bars 89 carried by a ring-member 81 which rotates with the member 80 about an axis which is eccentric to that of the shaft 72 and inclined thereto, whereby the rotation of the reel advances the material therealong, as described in Specification 413,414, [Group IX].  The inclination of the axis of the ring-member is adjusted by means of arms 97, Fig. 13, adapted to be moved over inclined ramps 100 may be individually and collectively operated.  The reagents are applied to the material as it travels along the reels by distributers 115 of any suitable form, and are drained from the <PICT:0474973/IV/3> <PICT:0474973/IV/4> and secured by screws 99.  The lowermost reel 5i is of generally similar construction, but the driving-shaft 72a is hollow and the central member 80a perforated for the passage of air for drying purposes, as shown in Fig. 2.  A limited amount of stretch spinning may be effected by making any one reel of tapered form. Specifications 413,413 and 475,024 also are referred to.
